Hi there,
I am having the weirdest and most annoying issue while trying to make my SC-55 work in my old 486 DOS gaming machine. I am using an ES1868F audio card as the MPU-401 interface, at address 330h (also tried 300h). When connecting my MT-32 via a db-15 to midi cable music is produced without any issue, so the cable seems to be in working order as well as the configuration. However, if I disconect the clable and connect it to the SC-55 midi-in no sound is produced 🙁 I have tried both with and without softmpu loaded in memory with identical results.
Well, that means it's a faulty SC-55 you may think. However, if I connect my laptop to the sc-55 unit through a usb-midi cable I can get sound out of the SC-55 without problems. Through both of the midi-in connections! It's the combination of the db-15 to midi which gives no sound, but the cable works fine with the mt-32. Is there any difference in the way that midi messages are sent through these two cables? I would have thought there is not, but can't figure out what is wrong.
Let's hope some of you have found a similar issue and can help me identify and solve it. Perhaps some misconfiguration of the sc-55?
Thanks in advance! Looking forward to hearing doom soundtrack in all its glory!
